No communication possible between power stage set and control system.

¿Qué significa 416 ?

This code indicates a failure in communication between the inverter's power stage set and its control system. This prevents normal operation, but the inverter will automatically attempt to re-establish communication and resume feeding energy into the grid.

• Faulty communication link (e.g., ribbon cable, bus connection) between the power and control boards.
• Malfunction of communication transceivers on either the power stage or control system.
• Electromagnetic interference disrupting the communication channel.
